Bottom Line

The avalanche danger will remain LOW for all elevations today and avalanche activity will remain unlikely. Other hazards still exist in the backcountry. Continue to use normal caution during backcountry travel.

Cold temperatures and increasing clouds and winds should keep crusts frozen and firm. While avalanche activity will remain unlikely today, other dangers like long sliding falls on the frozen crusts, collisions with some of the numerous exposed obstacles, or both still exist. Continue to plan travel in the backcountry to minimize risks.

The new snow expected tonight combined with increased SW winds may start to form small isolated wind slabs near exposed ridgelines. These wind slabs should not grow large enough to pose much of a hazard to backcountry travelers tonight due to the limited amount of new snow accumulation expected.

* Snow coverage on E-SE-S-SW-W aspects varies significantly by location and elevation. In some areas, little to no continuous snow cover exists on these aspects below 8,200' to 9,000'. In some cases, these aspects are mostly bare ground up to elevations above 10,000'.

Strong NE winds during the night have given way to moderate SW winds this morning. These SW winds should increase today as a small cold front approaches the area. The forecast calls for colder temperatures and a chance of snow starting tonight as the system arrives. Snow showers and clouds could linger over the area through tomorrow. This system does not have much moisture associated with it so snow accumulations may remain light with only up to 2 inches expected overnight and another possibility for up to 2 inches during the day tomorrow in some areas. By tomorrow afternoon the winds should shift back to the NE.
